Hello,
I am trying to setting up a template project to work with the SPI and DMA triggered by a timer using the STM32F746ZG. The configuration I need to program is the one in the attached image.
Need to trigger a DMA using the TIM7 making a request in channel 1in order to use the Stream2 to make a transfer from memory to the SPI3 peripheral. I set up the project with the STM32CubeMX and I can see the configuration for link the DMA request channel to the TIM7 but there is no code to configure the SPI3 and the memory to access the Stream2.
I searched for some examples but I could only find some using the SPL. Anyway the structure for the DMA configuration seems to be a bit different because in the SPL I can see the
DMA_PeripheralBaseAddr
field while not in the HAL Cube.
Can anyone give me a clue about how to configure the Stream of the DMA peripheral??
Thanks in advanced,
Omar
